Exactly right. There is absolutely no possible way to have an equal hardware
event. Not practically, not theoretically. Even if the organizer could afford to
buy the same machine for everyone, it wouldn't be fair.

No matter what you do, you will get complaints.

"My engine runs better on P4..."
"My engine runs better on Athlons..."
"My engine runs better on Xeon..."
"My engine runs better on Opteron..."
"My engine supports multiple CPUs, this isn't fair! I spent a lot of time
working on multiple CPU support!"
"My engine doesn't support multiple CPUs, this isn't fair!"
"My engine runs better on 64-bit hardware..."
"My engine doesn't get as big of a boost on 64-bit hardware as others do, this
isn't fair!"

And so on...

The only way to do it is to treat each participant as one chess player. One
author's strategy may be to focus on software imrpovements, another may choose
to focus on hardware improvements (Brutus, Deep Blue, etc.).
